This is a delightful insertable. The length is 110mm (4.3 inch), the tip is 20mm (0.8 in) and the neck is 12mm (0.5 inch). The 3 bands spread out the sensations evenly avoiding sharp spots and allowing for sensation as well as simple muscle contraction.
Choose which two of the 3 you want to use on one channel, and pair the 3rd with another accessory if you like and use it tri-phase. A must have for any toybox!
